Direct replacement for DX70i and WDX70i projectors

This lamp-and-housing module is built for the 3M DX70i and WDX70i models. It arrives as a complete assembly so the projector can return to full brightness without separate bulb handling. Schools, offices and home-theatre owners who run these specific units will find a drop-in fit.

Verify the exact projector model before ordering

Confirm the projector label reads DX70i or WDX70i; other 3M models use different lamp codes. The part number 78-6969-9994-1 must match the sticker on the existing module. No tools beyond a screwdriver are typically required, but the projector must be cool and unplugged before starting.

Replaces a dim or failed original lamp module

When the current lamp reaches end of life or the warning indicator appears, this unit restores factory-rated output. The swap is worthwhile if the projector otherwise functions correctly and the 90-day warranty period covers the installation window. Buyers needing higher lumen output than the original design cannot achieve it with this replacement.
